我试图使用Keras（Sequential），但在尝试导入它时出现以下错误：

我正在使用 Python 2.7、TensorFlow 1.1、Keras 2.0.3，并于昨天“升级”到 Pandas 0.20.1，我怀疑这可能是导致问题的原因，但错误信息并没有提到这一点。

你是如何更新 pandas 的？你确定你的 Anaconda 中的 Python 可以访问它吗？ - Dadep

我使用了conda和pip。我只是使用.__version__来检查pandas版本，并返回0.20.1。 - Greg

这是因为Pandas（0.20.1）的新版本发布了。上周五发布了Dask的新版本来修复在新版Pandas中出现的故障。将Dask更新到0.14.3版本应该可以解决您的错误。 - jiminy_crist

dask-0.14.3可以正常使用并且消除了导入错误。

我回退到Pandas 0.19.2版本，问题得以解决。

我认为更好的答案是按照这里所示更新dask：https://dev59.com/questions/v1cP5IYBdhLWcg3wyc7W#44615129 - lurknobserve

The full command I use is

conda install pandas=0.19.2

回答y以降级pandas，现在它可以工作了。

我安装了以下版本：

python 3.5
tensorflow 1.2.1
pandas 0.21
dask 0.15.3

但我遇到了以下错误：

pd.core.computation.expressions.set_use_numexpr(False)
AttributeError: 'module' object has no attribute 'expressions'

我降级到 pandas 0.19.2 和 dask 0.15.0 版本后，Python脚本可以正常工作！

升级dask到0.15.0版本将解决此问题

升级命令：conda update dask

输入 pip show dask 将显示以下消息
